Eligibility
Inclusion criteria
* Female individuals aged 18-30 years * Voluntary agreement to participate in the study and approval of the online informed consent form For the bruxism group: * Self-reported teeth clenching and/or grinding behavior during wakefulness or sleep within the past 6 months * Presence of clinical findings supporting bruxism (e.g., tooth wear patterns, masseter/temporalis muscle tenderness) identified during a clinical examination conducted at the Faculty of Dentistry For the non-bruxism group: * No self-reported teeth clenching or grinding behavior * Absence of clinical findings supporting bruxism upon examination Bruxism classification will be performed in accordance with the current international consensus, based on self-report combined with clinical findings, within the framework of "probable bruxism" (Verhoeff et al., 2025).
Exclusion criteria
* Diagnosed temporomandibular joint (TMJ) dysfunction or significant jaw pain syndromes * History of major pelvic surgery; early postpartum period (\<1 year) or current pregnancy * Neurological disorders (e.g., multiple sclerosis, peripheral neuropathies) * Presence of active urogenital or colorectal infection/disease * Diagnosed pelvic floor pathologies (e.g., advanced pelvic organ prolapse, severe urinary/fecal incontinence) * Chronic use of opioids, anticholinergic agents, or muscle relaxants * Severe psychiatric disorders (e.g., diagnosed major depressive disorder, generalized anxiety disorder) * Receipt of any bruxism-related treatment within the past 6 months (e.g., occlusal splint therapy, botulinum toxin injections, intensive physiotherapy)
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Bruxism Assessment Section | 6 months | Sleep and awake bruxism will be evaluated according to the bruxism diagnostic criteria established by the American Academy of Sleep Medicine (AASM) in 2023. Bruxism-related pain will be subjectively assessed using the Visual Analog Scale (VAS). The Visual Analogue Scale (VAS) is a 10-cm used to measure pain intensity, where 0 represents "no pain" and 10 represents the "worst imaginable pain. Patients mark their pain level, which is measured in cm or mm to determine the score. |
| Jaw Function Assessment Section | 6 months | Jaw function will be evaluated using the Jaw Functional Limitation Scale-20 (JFLS-20). The Jaw Functional Limitation Scale-20 (JFLS-20) scores range from 0 to 200 (or 0-10 average per item), with higher scores indicating more severe jaw functional limitation. It measures 20 items across three constructs-mastication, vertical mobility, and verbal/emotional expression-using a 0-10 scale, with 0 meaning "no limitation" and 10 meaning "severe limitation |
| Pelvic Floor Assessment Section | 6 months | Pelvic floor symptoms will be assessed using the Pelvic Floor Distress Inventory-20 (PFDI-20) and the relevant items of the Pelvic Pain Impact Questionnaire. The Pelvic Floor Distress Inventory-20 (PFDI-20) is a questionnaire measuring the severity of pelvic floor dysfunction, with total scores ranging from 0 to 300 (0 = no distress, 300 = maximum distress). It includes three subscales-POPDI-6, UDI-6, and CRADI-8-each scored from 0 to 100, calculated by multiplying the mean of answered items (0-4) by 25 |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Anxiety Assessment Section | 6 months | Anxiety levels will be assessed using the State-Trait Anxiety Inventory (STAI - State Anxiety Scale). The State-Trait Anxiety Inventory (STAI-S) assesses temporary, immediate, or situation-specific anxiety using a 20-item self-report questionnaire with 4-point Likert-type responses. Scores range from 20 to 80, with higher scores indicating higher levels of anxiety. A cutoff of 39-40 is often used for detecting clinically significant symptoms. |
